.func/.endfunc are gcc/gas-specific directives for generating stabs debug information (and nothing more). This is near-useless now because DWARF is commonly used, and not implemented in Clang. Hence building OpenBLAS with Clang fails, and there is no sane way to detect GCC vs. anything else with preprocessor definitions. Hence, just remove these directives.
